Improved means for driving paddle-wheels



UNITED STATES PATENT OEECE.

JOSEPH M. STORY, OF CINCINNATI, OHIO.

Specification forming part of Letters Patent No. 56,118, dated July 3, 1866.

To all whom it may concern.-

Be it known that I, JOSEPH M. STORY, of Cincinnati, county of Hamilton, and State of Ohio, have invented a new and Improved Method of Driving the Paddle-Vheels of Boats, whereby the power is applied nearer the periphery of the wheel than in the usual crank attachment, thereby driving a wheel o f the same dimensions with much less power than in the ordinary manner; and I do declare that the following` is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference markedthereon.

Figure l is a side elevation of my invention, showing the paddle-wheel A, the large friction-wheel B, the two small driving frictionwheels C D, the driving-pulley E, the levers F G, for the purpose of applying the power to the large friction-wheel B by means of connecting-shafts a b and small levers c d. The arm AX of paddle-wheel is represented broken off, in order to show more plainly the opera tion of the friction-wheels C D and levers c d. The operation of these levers and frictionwheels is shown in red lines. The crank J (shown in dotted lines) indicates the point at which the pitman of the engine is attached.

Fig. 2 is a plan or top View, showing the paddle-wheel A, the frictionwheels B C D, the pivot-boxes H I, which support the end of the shafts e j', opposite the movable ends, which are supported and operated by the lcvers c d, Fig. l, the belts g h, running from the driving-pulleys E E to friction-wheels'C D, the levers F Gr, and their connections with friction-wheels C D.

Fig. 3 is a sectional`view of small wheel C, taken through center line, w zu, Fig. 1, show ing the operation of the same with dotted lines P P. The box H is a pivot-box, which permits the movement of the shaft by the levers c d, Fig. l.

In order that others may fully understand and be enabled to construct and use my invention, I will proceed to explain the operation of thesame.

I use the ordinary form of paddle-wheels, and upon the shaft S, Fig. l, I put a frictionwheel, B, as largeA as the nature of the case will admit, and below this wheel I use two smaller friction-wheels, C D, for the purpose of driving it. One of these wheels, C, drives the large wheel in one direction, the other, D, driving it in the reverse direction. These wheels C D are placed on shafts c f, Fig. 2, that are supported by stationary pivot-boxes at one end, H I, Fig. 2, and pivot-boxes attached to the levers c el at the opposite end. This is for the purpose of communicating and discontinuing the power to the large wheel at the will of the operator; also, for reversing the direction of the wheel. The levers o al are operated by means of the shafts a b, which connect them with the levers F Gr, and these are worked by the operator (who may be stationed in the pilot-house or other conve-nien t place) by means of ropes attached to them and connecting with any kind of apparatus by which the necessary power can be applied to operate the levers and friction-wheels C D. The large friction-wheel B is driven by small wheels C D, either for ward or "backward, by bringing either the one or the other in contact with it. The wheels C D are driven by means of belts ghru'nning from the driving-pulley E. One of' these belts being crossed gives opposite directions to the wheels C D.

What I claim as new, and desire to'secure by Letters Patent, is"- Applying the power to the paddle-wheels of boats near the periphery of the same by means of friction-wheels and levers, in the manner and for the purpose substantially as herein set forth.
